I was running the dual Spal fans with a Spal controller. The are some serious fans that need dedicated electrical circuits with dual relays.

I never had an issue with cooling even on the hottest days with A/C on, but am switching back to the new Hayden stubby clutch, metal fan and stock shroud. If you have room, its hard to beat.

They are still on the car, but are going up for sale very soon.
